Michael McCandless commented on LUCENE-6908:
--------------------------------------------
Hi [~nknize], I think you forgot to add {{GeoRelationUtils.java}} before making
the patch? And also, can you make the patch from higher up in the source tree?
It seems to be missing e.g. changes to {{SloppyMath.java}}.
> TestGeoUtils.testGeoRelations is buggy with irregular rectangles

>
> The {{.testGeoRelations}} method doesn't exactly test the behavior of
> GeoPoint*Query as its using the BKD split technique (instead of quad cell
> division) to divide the space on each pass. For "large" distance queries this
> can create a lot of irregular rectangles producing large radial distortion
> error when using the cartesian approximation methods provided by
> {{GeoUtils}}. This issue improves the accuracy of GeoUtils cartesian
> approximation methods on irregular rectangles without having to cut over to
> an expensive oblate geometry approach.
